v1.11.1

⚠️ BREAKING CHANGES ⚠️

• Overhaul all form components to follow a state-led onChange handling, instead of mucking around with direct DOM
  events, meaning instead of onChange={e => doSomething(e.target.value)} you can now just do onChange={value => setValue(value)} and do whatever you want using the useState hook.

GENERIC CHANGES

• Add CheckboxGroup and SwitchGroup components, that work in the same way as RadioGroup
• Add FileUpload component with drag-and-drop support
• Revamp FileUpload with drag-and-drop support and multiple file upload support
• Textarea now has a charLimit and wordLimit props, along with warning and error messages
